Most placeholder tools generate one image at a time. PlacePack lets you paste an entire dimension list with aliases, retina variants, and per-image color overrides and download everything as a single ZIP of PNGs or SVGs in seconds. No login. No API calls. Presets for common workflows (Storybook, social media, LinkedIn, Pinterest). Share the full config as a URL so your team always generates the same assets. Built for designers and developers who hate busywork.
